8Z-27.120MAAQ-T

Crystals Overview

The 8Z-27.120MAAQ-T is a surface-mount quartz crystal manufactured by TXC Corporation, designed for precision frequency control in electronic circuits. It operates at a nominal center frequency of 27.12 MHz with a frequency tolerance and stability of ±30 ppm at both 25°C and the -20°C to +70°C operating range. The component features a 4-SMD, no-lead package with dimensions of 3.2 mm x 2.5 mm x 0.9 mm. It utilizes a load capacitance of 10 pF and has an equivalent series resistance (ESR) of 100 Ohms. This device is suitable for applications requiring reliable clock signals within standard commercial temperature limits.

Crystals Feature Summary

• Seam seal ceramic construction provides robust physical protection and environmental stability.
• Surface-mount design facilitates automated assembly and compact PCB layout integration.
• Base fundamental mode operation ensures stable oscillation characteristics.

Crystals Applications

• Clock generation for microprocessors and microcontrollers
• Frequency reference sources for communication modules
• Timing circuits in consumer electronics devices

Crystals Procurement Notes

Verify that the specific part number matches the required electrical parameters, particularly the 100 Ohm ESR and 10 pF load capacitance, as these differ from other variants in the 8Z series. Confirm compliance with RoHS3 and REACH regulations if required by your supply chain standards. Ensure the ordering suffix corresponds to the correct packaging format, such as tape and reel, for your manufacturing process.

Crystals Selection Notes

Select this component when a 27.12 MHz frequency is specifically required for the system architecture. The ±30 ppm stability is adequate for general-purpose timing but may be insufficient for high-precision synchronization applications requiring tighter tolerances. Consider the 100 Ohm ESR value to ensure compatibility with the oscillator circuit's drive level requirements, typically around 10 uW, to prevent overdriving the crystal.

Crystals Part Context

This component belongs to the 8Z series of seam seal crystals from TXC Corporation. These devices are characterized by their small 3.2x2.5 mm footprint and ceramic sealing technology, which offers improved reliability compared to older metal can packages. The series is widely used in portable electronics and industrial equipment where space constraints and environmental durability are critical factors for component selection.

Crystals Replacement Considerations

Direct substitutes with identical specifications include the 8Z-27.120MAAV-T, which shares the same frequency, package, and electrical characteristics. Other compatible alternatives in the market may include parts from manufacturers like QST, provided they match the 27.12 MHz frequency, 10 pF load capacitance, and 100 Ohm ESR requirements exactly.
